2010-08-17 17:30:28 what is nfs root boot?
Matt Prewett (UNITED STATES)
I was looking at the following document:
and saw the section about doing an "nfs root boot".
I searched around and could not find any information about what this is and what are the advantages of doing it.
Does anyone have any information about this? Does this assume I am compiling the kernel myself? Currently, I am just using the pre-compiled uClinux binary from the website.
Thanks in advance,

"nfsboot" is a helper specific to Blackfin's u-boot env, so you wont find much out there. "nfs root" though is a standard thing that all Linux systems can support.
basically it means that your root filesystem is completely hosted over nfs. there is no need for local storage (either a compiled in initramfs root or some local flash fs or ...) as everything is on the network. in terms of development time, it's just a matter of preference whether you do it all out of ram or over the network or some combination.
the file the wiki refers to contains some more info (linux-2.6.x/Documentation/nfsroot.txt).
